“…In this regard, some studies with the aim of recovering aluminum compounds have been published in recent years. [9][10][11][12][13][14][15][16][17][18][19][20] However, the high amount of Al slag generated worldwide requires searching for new methods of valorization. The published research is limited to the use of Al slag as an asphalt filler, 21 an adsorbent for the removal of Cd(II) or organic compounds such as Congo red dye from aqueous solution, [22][23][24] or in the manufacture of value-added products such as refractories, 25 Sialon, 26 expanded clay aggregates, 21 cement and concrete, 27,28 geopolymers 29 and spinels.…”

“…The recovery of valuable materials from industrial waste has been the purpose of several research works due to both environmental requirements and economic viability. In this regard, some studies with the aim of recovering aluminum compounds have been published in recent years 9–20 . However, the high amount of Al slag generated worldwide requires searching for new methods of valorization.…”

“…Using plasma for the production of alumina has lower residue as well as lower production and maintenance costs compared to traditional gas and oil burners [87]. Saravanakumar et al [88] converted aluminum dross into ultrafine alumina powder using a plasma arc melting process. It was reported that the amount of the conversion of Al dross to alumina powder substantially correlates with plasma power.…”

“…The valorization of industrial waste is a sustainable way to wisely utilize renewable resources. Aluminum dross is a toxic industrial waste generated from aluminum refining industries that contain aluminum oxynitride (AlON), aluminum oxide (Al 2 O 3 ), aluminum metal (Al), and impurities such as potassium chloride and sodium chloride [88]. Based on reports nearly 95% of aluminum dross is landfilled without treatment that is hazardous to the environment in China [99].…”
